Patented May 3, 1938 UNITED STATES PATENT OFFICE WATCH Frank Wachter, New York, N. Y.; Theresia Maria Wachter administratrix of said Frank Wachter, deceased 4 Claims.

This invention comprises an improved watch crystal and has for its object to provide a crystal into which the movement of a watch is disposed and supported, which provides a greatly simpli- 5 fled construction for use in combination with other parts to form a complete watch unit.

The present invention comprises a watch casing including a transparent tubular member adapted to form the watch crystal and to receive the movement edgewise.

Said casing is also provided with closure means and a frame which is adapted to carry said transparent tubular member.

By having the crystal so that it will receive the movement edgewise, it will be understood that watch movements of the general form are fiat, that is in dimension from face to back much smaller than the dimension of across the dial or across the frame of the movement, so that the periphery is referred to as an edge. This rela tively narrow edge thus may be inserted in the end of the crystal, which is in effect a narrow pocket adapted in cross-section to conform to the cross-section of the movement, or movement and dial taken normal to the dial face. With a portion attached to the movement as a cap or closure I9, it provides a handle so that when the works have been inserted edgewise the cap cooperates with that end of the tubular crystal and holds the watch in a predetermined position within the crystal, with the front and its dial as well as the back of the works being closely confined by the tubular crystal, in a manner so that the watch movement when so assembled is substantially waterproof, but by means of the closure the entire movement. works and frame, with dial and hands may be pulled out from its set position in the tube, for the purpose of inspection, repair or replacement. Being so inserted edgewise, and with the closure I9 fitting the slot at one end of the tube, the predetermined position in the tubular crystal is maintained.

The drawing shows a perspective view of a watch, showing the parts in their respective positions in which my tubular transparent watch crystal so formed as to receive the movement with its dial edgewise is shown in course of assembly with the other parts of a watch.

In the embodiment of this. invention as shown upon the drawing, the transparent tubular member I1 is the watch crystal preferably closed at its lower end, or it may, if desired be open at its lower end as well as at the top end, but as shown it lies close over the face of the watch movement.

The transparent tubular member I1 is mounted in a metal frame 20 in which an aperture is provided to expose the watch dial, and as. shown the back of the transparent tubular crystal also registers with an aperture in frame 20, so that it makes the back of the works or movement visible through the tubular crystal. The lower end of said frame is closed, whilst the upper end of the frame 20 is open to receive the insertion of the transparent tubular member ll when assembling the watch.

A closure I9 is provided for the transparent tubular member I1, and mounted on said closure I 9 is the watch movement frame l8. The closure l9 may snap into the transparent tubular member l7 thereby supporting the watch movement with its frame, as shown, in fixed position in the tubular crystal.

As shown in the drawing the watch movement with its frame in shape and size fits snugly the interior of the tubular crystal.

Hinged to the frame 20 is a cover 2| which is adapted to cover over the closure l9 and be locked to the frame 20 by means of a snap or other suitable fastening.

The transparent tubular member I! may be made of glass or other suitable material and is of such tubular form that it is adapted to receive a watch movement edgewise so that it closely conforms to the outer formation of the conventional or almost universally used watch movement, as herewith shown and described.

I claim:-

1.. A watch comprising a movement with dial, a transparent tubular watch crystal of a form 5 and construction adapted to receive the movement and dial edgewise, means closing the ends of the tubular crystal, including at one end means attached to the watch movement and adapted to register with that end of the crystal to hold the 40 movement in a predetermined position in the crystal, and a frame adapted to partially surround the tubular crystal with an opening ex tending substantially throughout one side and adapted when assembled to provide visibility throughout that side of the works having a super posed dial.

2. A watch comprising a movement with a dial, a transparent tubular member, means. to close one end of the tubular member including a cover plate attached to the watch movement and adapted to hold said movement in position in the transparent member, and an outer frame having an opening through one side to provide visibility of the dial.

adapted to receive a watch movement edgewise, means sealing said tubular crystal airtight at each end, including at one end a removable covering having a Watch movement associated therewith and positioned thereby in the tubular crystal, and an outer frame having an opening at one side to provide visibility through a side of said tubular crystal.

FRANK WACHTER.
